Caryopteris plant named &#39;dcarocean&#39;

ABSTRACT

A new and distinct  Caryopteris  cultivar named ‘DCAROCEAN’ is disclosed, characterized by deep violet flowers and short spacing between inflorescences. The new variety is a  Caryopteris , normally used for ornamental horticulture purposes.

Latin name of the genus and species: Caryopteris incana.

Variety denomination: ‘DCAROCEAN’.

BACKGROUND OF THE INVENTION

The new Caryopteris cultivar is a product of a planned breeding program conducted by the inventor, Gavriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new Caryopteris varieties for ornamental commercial applications. The open pollination resulting in this new variety was made during August of 2011.

The seed parent is the, unpatented, proprietary variety referred to as Caryopteris ‘CT-Z-16’. The pollen parent is unknown as it was an open pollination breeding program. The new variety first flowered July of 2012. The new variety was selected August of 2012 by the inventor in a group of seedlings resulting from the 2011 open pollination, in a research greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar was performed by terminal vegetative cuttings. This was first performed at a research greenhouse in Moshav Mishmar Hashiva, Israel during Fall of 2012 and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DCAROCEAN’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DCAROCEAN’ These characteristics in combination distinguish ‘DCAROCEAN’ as a new and distinct Caryopteris cultivar:

1. Deep Violet flowers.

2. Distinctively short space between inflorescences.

Plants of the new cultivar ‘DCAROCEAN’ are similar to plants of the seed parent, Caryopteris ‘CT-Z-16’ in most horticultural characteristics, however, plants of the new cultivar ‘DCAROCEAN’ differ in the following;

1. Longer stems than the seed parent.

2. Compact space between inflorescence, whereas the seed parent has elongated space between inflorescence.

Plants of the new cultivar ‘DCAROCEAN’ are comparable to the unpatented commercial variety Caryopteris ‘Blue Myth’. The two Caryopteris varieties are similar in most horticultural characteristics; however, the new variety ‘DCAROCEAN’ differs in the following:

1. Shorter spacing between inflorescence.

2. Thicker, harder, quality to stems. The comparator has thinner, softer stems.

Plants of the new cultivar ‘DCAROCEAN’ can also be comparable to the unpatented commercial variety Caryopteris ‘Heavenly Blue’. The two Caryopteris varieties are similar in most horticultural characteristics; however, the new variety ‘DCAROCEAN’ differs in the following:

1. Thicker, harder, quality to stems. The comparator has thinner, softer stems.

2. Wide leaves, whereas the comparator has narrow leaves.

3. Violet flowers, whereas the comparator has blueish flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DCAROCEAN’ grown outdoors in Israel. Age of the plant photographed is approximately 5 months old from a rooted cutting.

FIG. 2 illustrates a close up of the flowers. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Mini Chart 2005 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘DCAROCEAN’ plants grown outdoors during Spring and Summer in Moshav Mishmar Hashiva, Israel. The growing temperature ranged from approximately 20° C. to 35° C. during the day and from approximately 17° C. to 23° C. during the night. General light conditions are normal sunlight and numerical values represent averages of typical plant types.
